Ooh, I really thought it was broken but now I see it, and it's super interesting!
I love maths so it's a great challenge
Hehe...

I figured out all of the operators and it was quite hard, but very absorbing. :D It's like in the Eleusis card game, you have to experiment and find the rules, but here you have to think out of the box a lot, as you don't know how far can stretch the rules
But I am afraid a lot of player will hit a brick wall and dislike the game without understanding it
I didn't have a "aha" moment because you never know if you have all of the rule, but I really enjoyed the challenge. Thank you! :)
